SUMMARY
Hey there, I notice regularly when writing with my stylus pen (which is exceptionally good supported btw) that my system freezes after some time. I use RNote to take notes and at some point, just nothing happens anymore, the clock in my dock doesn't update and I can't interact with my system in any way anymore.
I unfortunately don't know which logs are required, but maybe I'm not the only one with this issue.
I haven't tested it on X11 (writing there is garbage)

Alternatively, sharing the screen with firefox might also be the issue. I enabled native wayland rendering and when I write, I usually share my screen with my partner. This might also cause the crash, it didn't crash when using chromium to share the screen when I remember correctly and this is way easier to test :)


STEPS TO REPRODUCE
1. start wayland session
2. write with stylus/share screen in firefox
3. wait for hang

OBSERVED RESULT
the whole system hangs, nothing responds to anything anymore, I need to restart

EXPECTED RESULT
The system keeps on responding

Can you please retrieve the backtrace of kwin_wayland when it's frozen? https://community.kde.org/KWin/Debugging you may need to ssh from another computer
